Spoke with Amazon support, both was declined (yay) but troubling that this did attempt to process. Amazon has said I needed to contact the site owners on why this amount was charged as their systems say that is what was requested.

Very odd situation, I attempted to purchase a Pi 4 case and used the amazon checkout to process payment. It failed twice and upon checking my email it looks like the listed charge for $19 and change ended up being $23,000. Unsure how to contact the site owners so hopefully they see this.
